To many scammers. Especially those with Lotus Europa's under $15,000.00. You know who you are. You work for oil company's so you cant be here for the sale, your "agent " will take the sellers money and ship the car. Your "agent" happens to be overseas and for some reason the car is always on the other side of the US.
If you want to avoid a scam just ask the seller for the VIN number like eBay does, If they don't have one odds are they don't have a car.
